Kohlberg Kravis Roberts has held a final close for its latest energy hedge fund with $2 billion.

The new fund will invest in oil and gas assets, primarily in North America, and brings to $8.7 billion KKR’s energy and infrastructure assets. In particular, the fund will focus on drilling joint-ventures, mineral acquisitions and royalties.

“The energy revolution has created an unprecedented opportunity set, and we are seeing many ways to partner with companies to help develop these important resources,” KKR energy and infrastructure head Marc Lipschultz said.
